How to use conditional statement within child attribute of a Flutter Widget (Center Widget)

Question

So far whenever I needed to use a conditional statement within a Widget I have done the following (Using Center and Containers as simplified dummy examples):

Answer 1

This is great article and conversation. I tried to use the ternary operator as described. But the code didn't work resulting in an error as mentioned.

Column(children: [ condition? Text("True"): null,],);

The ternary example above is miss leading. Dart will respond with an error that a null was returned instead of widget. You can't return null. The correct way will be to return a widget:

Column(children: [ condition? Text("True"): Text("false"),],); 

In order for the ternary to work you need to return a Widget. If you don't want to return anything you can return a empty container.

Column(children: [ condition? Text("True"): Container(),],); 

Good luck.
